Effects of Magnetic Interactions between Ferromagnetic Spherocylinder Particles on Orientational Distributions of a Nondilute Colloidal Dispersion

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2007
We have analyzed the time-dependent behaviors of the ferromagnetic spherocylinder particles which make a nondilute colloidal dispersion influenced by the external magnetic field. In order to understand the effects of the magnetic interactions between the particles, we have derived a basic equation for the orientational distributions of the particles in

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
